标准摘要
[中文适用范围]： ISO 9455 的这一部分规定了软焊剂功效的测定方法。 该方法称为填充金属焊料铺展法，适用于 ISO 9454-1 中定义的所有助焊剂类别。 注：ISO 9455-16 中规定了一种确定助焊剂功效的替代方法，仅适用于液体助焊剂，称为润湿平衡法。 [3] [外文原描述]： This part of ISO 9455 specifies a method for the determination of the efficacy of a soft soldering flux. The method is known as the solder spread method of filler metal and is applicable to all flux classes defined in ISO 9454-1. NOTE An alternative method for the determination of the flux efficacy, applicable to liquid fluxes only, known as the wetting balance method, is specified in ISO 9455-16.[3]
